IIARMER. DEUNEY, OF BROOKLYN, JEW' YORK.

CLUTCH.

SPECIFICATION forming part of Letters Patent No. 446,664, dated February 1'7, 1891.

Application filed May 28, 1890- T0 to whom it may concern.-

Be it known that I, HARMER DENNEY, of Brooklyn, in the county of Kings and State of New York, a citizen of the United States, have invented certain new and useful Improvements in Clutches, of which the follow ing is a specification.

This invention relates to improvements in clutches such as are used for driving one piece of machinery from another, and especially where the direction of rotation of certain parts of the machinery is to bereversed rapidly and without lost motion.

The invention consists in the construction and combination of parts and details, as will be fully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a vertical transverse sectional view of the same on the line 3 3, Fig. l; and Fig. et is a similar view on the line at a of Fig. 1.

Similar letters of reference indicate corresponding parts.

The spindle or shaft ll is provided with two collars N and O, which are fixed thereon, and between the same an eccentric P is fastened on said spindle, and said eccentric I is surrounded by another eccentric Q, which is loose thereon. The two eccentrics are so arranged that the thicker part of one eccentric is adjacent to the thinner part of the other, as shown in Fig. 4, and the circumference of the outer eccentric Q is concentric with the spindle or shaft H. The outer eccentric Q is provided with an outwardly-projecting lug Q, which is arranged between the adjacent ends of two collars S, mounted to turn with and to slide lengthwise on two sleeves R, mounted loosely on the shaft or spindle H, and which sleeves are each provided with a cog-wheel R, engaged with gearing for rotating them in opposite directions. Each collar S has a circumferential groove, into each of which the prongs of a fork S pass, said forks being secured on a longitudinally-sliding rod S As shown in Fig. 2, the spindle or shaft H Serial No. 353,420. (No model.)

is engaged with the right-hand sleeve R and is rotated with the same, the left-hand sleeve B being disengaged from the shaft or spindie. If now .the rod S is moved in the direction toward the right, both the collars S are moved toward the right, and the pin S on the righthand collar S is moved out of the path of the lug Q on the eccentric Q, and the pin S on the left-hand collar S is moved into the path of the lug and will eventually strike that lug, thereby turning the outer eccentric Q. slightly on the inner eccentric P, thereby causing said eccentric Q to bind on the left-hand sleeve R, at the same time disengaging the eccentric Q from the right-hand sleeve It, so that thereby the motion of the spindle or shaft H is reversed. If the rod S is moved in the direction toward the left, the pin on the left -hand collar S is moved out of the way of the lug Q, and the pin S on the right-hand collar S is moved in the path of the lug O, which it strikes, thereby turning the eccentric Q so that it binds on the right-hand sleeve R and is disengaged from the left-hand sleeve R, whereby the direction of rotation of the shaft or spindle His again. reversed.

The above-described reversing-clutch has also been shown and described in my application, Serial No. M1934, iiled December 27, 1889, for a machine for making tubing; but I do not claim theherein-described invention in the said application No. $41,934:.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a shaft or spindle, of an eccentric fixed on the same, a reversed eccentric mounted loosely 011 the eccentric fixed on the shaft and having a proj ection, two sleeves mounted loosely on the shaft or spindle, means for rotating the sleeves in opposite directions, and sliding collars keyed on said sleeves and having pins projecting toward each other, the projection on the loose eccentric being between said sliding collars, substantially as set forth.

2. The combination, with a spindle, of a fixed eccentric on the same, a reversed eccentric mounted loosely on the eccentric fixed on the spindle and having a projection, two ulyinvontion I have signed mynzune in pressleeves on the spindle at opposite sides of the ence of two subscribing witnesses, eccentrics, means for turning the outer eccentric to bind on either one of said sleeves, and I IARMER DENNEY. means for rotating said sleeves in opposite Vitnesses: directions, substantially as set forth.

In testimony that I claim the foregoing as JOHN A. STRALEY.
